What to do if all the above methods fail to Remove Write Protection Error?

In case if all the methods get failed to fix the error, then you should leave the hope of fixing your Pendrive or SD Card. Actually, all the NAND devices like SD Card or Pendrive comes with a limit of Write or Erase and this limit ranges from 10K to 100k.

This means, you can Format your SD Card or Pendrive only 10000 times and when the limit reaches, the drive comes back to the Readonly state. So you can’t format it. That’s why I suggest you download branded SD cards or Pendrive because they have high Erase Limits.

So that’s it for today, I hope this would have fixed your Write Protection Error.
